Linux 3.2.83-rt121-rc1

Dear RT Folks,

This is the RT stable review cycle of patch 3.2.83-rt121-rc1.

Please scream at me if I messed something up. Please test the patches too.

The -rc release will be uploaded to kernel.org and will be deleted when the final release is out. This is just a review release (or release candidate).

The pre-releases will not be pushed to the git repository, only the final release is.

If all goes well, this patch will be converted to the next main release on 11/2/2016.

Enjoy,

-- Steve

gcc warns about casting directly from a 32-bit pointer to u64. In the current rt patch series we cast to unsigned long to avoid the warning, but this fix hasn't been backported to all versions.
